This invention relates to anew and improved knitted fabric and the method of pro- 'ducing' the same.

'The main object of the invention is the i production of anovel and attractive fabric.

' Other-objects'and advantages relateto the Ydetails of the method whereby the fabric is produced, and to the specific detailsof the structure ofthe fabric, allas will more fully appear from thefollowing descriptiom taken in connection with the accompanying draw- .'ing's,in.-which:

Figure 9 is agrea tly enlarged view "o'f a section'of fabric. 1 a The apparatus used in-accomplishing the invention is in the nature of a combination of: thestandard knitting machine having cir cularly'arran'ged needles and of other special mechanism,'and in Figure 1 such mechanism 9 is shown "asapplied' to such almachine em,

b'odying' needles -1- of a usual and ordinary construction, saidneedles embodying a {flexible.resilientbeard e20 under which the thread is placed for the formation of threadis" placed under the beards- 20 of the needles. by means of stitch wheels 2, 8 and 4 rspectivelyillustrated in Figure l Eachirstitch wheel in the ordinary. knitting machine is designed for--placing its particua ff this mechanism at blades of both the in the usual manner." The Serial No. 515,203.

lar thread under the heard of each needle for the formation of a knitted loop upon each needle when the cloth is moved from the depressed portion in which it is held by the shoe or plate, and the last formed knitted loops will be near the bottom of the needle, such last formed knitted loops being cast off after the thread has been placed underneath the beard of the needle, all inthe usual man ner.

For thepurpose of illustrating one form of my invention which at present is deemed satisfactory for the production of a novel and attractive cloth, I have shown three stitch wheels 2-, 3 and +,.one of which, 6 as the wheel -2 is adapted to place a thread under the heard .20 of every other needle.

In other words, the stitch wheel -2 places its thread under the beard 20 of one needle, skips the next needle, then places its thread under the beard of the succeeding needle thereby forming two knitted loops separated by a pile loop.

, This is-efiected by placing a plug 7 in the space between-certain of the blades of the wheel, and in this particular illustration a plug is placed between alternate pairs of Wheels 2 and -3-. These plugs -7- are shown in Figures 1 and 5 andmay be secured between the blades 3 8 ofan ordinary stitch wheel'in any suitable manner, andas illustrated the plug is formed with alaterally extending lug or flange 9 which isadapted tofit in an opening in one of the adjacent blades, and is there by held in that position when the'wheel is assembled in'the usual and well known manner.

The plug 7. is of such a form that when the projecting end portions 10 of the stitch wheel bring the thread adjacent the lower. end ofthe beard 20, the plug -7- movestheend of the beard a 'ainst the body of theneedle and into the usualrecess formed therein sothat the thread instead ofbeing forced or moved under the heard 20. slips up outside the beard, and a knitted loop is not formed upon that needle by that thread,

one Isideof the. resultant fabric.

These plugs, as stated, maybe placed in alternate spaces between the blades of the ordinary stitch wheel and the construction of the stitch wheel 3 is the same as that oi the stitch wheel 2 so "far as its physical I formation is concerned. b

However, its arrangement with respect to the needles is such that itplaces a thread under the beard of the needle and thereby forms a] knitted loop upon the needle which the stitch wheel -2 skips, and then skips the needle upon which the stitch wheel 2- has placed a knitted loop,'or in other words it moves a thread under the heart -'fi20 whereby a knitted loop is formed so that the wheel forms a pile loop where the wheel forms a knitted loop. 7 In other words, in this particular illustration, twoplugged stitch wheels, provided with: suitably arranged plugs, are utilized, and-the wheel -2- places a knitted loop on one needle and skipsthe next, andcontinues that all the way around'theneedles oi the, machine, while the wheel places a knitted loop upon the needle which the wheel 2 has skipped", and then skipsrthe'next needle and" continues that operation: all the way around the needles ofthe machine.

r The stitch wheel t 'is not providedwith any plugs-but is of the usual term adapted to move the thread under the beard 2O of every needle so-that it forms a lniitted loop uponevery needle.v

In other words, the wheel produces with; lliS'tllIGdCl a regular, uniform series of knitted loops and the wheel -:2- forms a series of pile loops upon one side of the fabric separated by knitted loops interlocked with alternate knitted loops tormed bythe wheel d', and likewise the wheel '-3' tormsa series of pile loops separated by knitted loops interlocked with ternateknitted loops -et-+ so that allot the threads are tied together into. and form an inseparable portion of thetabric,

In the usual manner the lastknit-t-e'd loop upon theformed fabric isiheld at the bottom w of the needles '.1'-*during' the time that the 'ncedleslel the presser plate -12 contactswith the beards} upon the needles and ino'ves'the ends otthebeards ihtoithe recesses usually formed in the-body ot the needles r and atthat time the landing whee-1 moves the: knitted loops which are at the; beam; ot'the needles 1 upwardly over the beards J1. V I a thus formed on wheels.

- place the other alformed by the wheelv A shortdistance beyond the landing Wheel ,13 is'a cast-off wheel (not shown) of the The operation continues by the knitted loops,

the needles being moved downwardly to the base of the needles bythe shoe or plate -6-, whiclrmoves the knitted loop so formed downwardly to the base of the needleand 'tlievoperation continues in the same manner the threadunderneath the beard of the par ticular needles desired by means of the stitch wheels eQ,.V-.I3V- and -4.,' or similar by't-he placing of i As illustrative of this particular embodi ment of my invention, the stitchwheel -2- a I o skips the needle --1i-, places athread under the beard of the needle -l'5y skips needle -16'- places a-thread underthebeard 0t needle -.17 and continuesinthis manner.

Itfwill be obvious that the wheels 2 andicontinuesin that manner while thestitchf vwheel places a-t'hread -under the beard I 25 and -3'v-'niay be provided with' plugs in any particular sequence. of spaces soras to r a thread underthe heard of every other needle, or every. third needle orotherwise,

as desired, for the tormationof a particular fabric. T

" It is essential, however, that onewheel be 1 used which places a' needle, andthiswheel may be in any relative position with respectto tliejo tiier wheels,

and produce the characteristic appearance of the cloth of my invention.

The length of the pile loop extending from one side of the fabric is governed by a longer orfsho'rterknitted loop on the Wheel l which puts a knitted loop under thebeard of every'needle, but that adjustment has onlv a small limit.

7-...for shorter pile loops and smaller plugs small plugs are used the plates of the stitch Wheel, When closing the beard so 1 that a knitted loop Will not be made,

InFigure 9 thereis illust-ratedyasmall portion of the fabric in Which the thread -4e0- is shown as formed into a regular, uniform While the thread Whichare interlockedwith alternate knitted lO. In a similar manner, the thread 22 is formed "into a seriesof pile loops 51 interlock with alternate knitted loops formed by the thread ''40, but being different alter- 'nate knitted loops than those With which the thread '2l is interlocked, whereby two 7 only necessary to turn the, machine until the graduation upon one I of the Wheels comes I r In order to get any great variation, it is necessary to make larger plugs loops. WVhen I forming a uniform series of knitted series-of pile loops are formed which extend to one and the same side of the fabric, both of Which are interlocked in thefabric by engagementwvithalternate knitted loops of the regular uniform formedby the'thread -4e0.

It willrbe obvious tothose skilled in the art thatby the use of my invention, various patterns of cloth of my invention can be made, that the skip ofpile loops and knitted loops may be in any desired sequence in accordance Withthe desires'of the maker, and thatany "desired number of ends and Wheels maybe used, and in any alternateor other relation desired, and that various changes, modifications and substitutions may be made in the details of the process, the machine, and

the-products, Without departing from the invention'as set forth in the appended claims.
